Abstract

A találmány tárgya eljárás arilszulfonil-izocianátok előállítására. Atalálmány szerint úgy járnak el, hogy egy arilszulfonamidot egykatalitikusan hatásos mennyiségű alkilizocianát jelenlétébenfoszgénnel reagáltatnak. A reakciót egy prótikus sav vagy sójakatalitikusan hatásos mennyiségének jelenlétében végzik és/vagy afoszgént úgy vezetik be, hogy a köztitermékként keletkező alkil-arilszulfonil-karbamid koncentrációja a reakciózónában a foszgénadagolási ideje alatt egy minimális érték alá ne csökkenjen. Atalálmány szerinti eljárás magas hozamot és terméktisztaságoteredményez. ÓThe subject of the invention is a process for preparing arylsulfonyl isocyanates. According to the invention, they proceed by reacting an arylsulfonamide with phosgene in the presence of a catalytically effective amount of alkylisocyanate. The reaction is carried out in the presence of a catalytically effective amount of a protic acid or salt and/or phosgene is introduced in such a way that the concentration of the intermediate alkyl arylsulfonylurea in the reaction zone does not fall below a minimum value during the phosgene dosing period. The process according to the invention results in a high yield and product purity. HE
